What do the wavy lines in math mean?
One wavy line (~) represents similarity. Two wavy lines (≈) means "approximately." THree wavy lines (≋) would most likely mean approximately identical to.
Is there a shape with 9999 sides?
Yes, a shape with 9999 sides is called a 9999-gon. In geometry, polygons can have any number of sides, and a 9999-gon specifically has 9999 straight edges and vertices. While such shapes are rarely encountered in practical applications, they are mathematically valid and can be studied in terms of their properties and characteristics.
The measure of each interior angle of a quadrilateral is than degrees.?
The measure of each interior angle of a quadrilateral is always less than 360 degrees, as the sum of all interior angles in a quadrilateral is 360 degrees. This means that each individual angle must be less than 360 degrees, but it can vary widely depending on the specific type of quadrilateral. For example, in a rectangle, each angle is 90 degrees, while in an irregular quadrilateral, the angles can differ significantly.
How do you find the volume of a cube when it is 1yd on its edge?
Being a cube, each edge is one yard long.
Volume = length X breadth X Depth.
Hence
Vol = 1 yd X 1 yd X 1 yd = 1 cu. yd. ( cubic Yard).
Where is the perimeter outside or inside?
The perimeter is both on the outside and the inside of a shape, as it is basically the outside wall/border of a shape and can therefore be viewed from the outside or the inside.
What is the circumference of a circle if its area is 81π?
C = 81 pi = 2pi r
Hence
2 pi r = 81pi
r = 81 pi / 2 pi
Cancel down
r = 40.5
A = pi r^(2)
A = pi ( 40.5)^(2)
A = 1640.25 pi units^(2)
The equation for the circle is x2 plus y2 equals 121 What is the length of the circle's radius?
x^(2) + y^(2) = 121
From the Cartesian coordinates
x^(2) + y^(2) + 2(0)x + 2(0)y = 11^(2)
It is if the form
x^(2) + y^(2) + 2fx + 2gy = r^(2)
r^(2) = 11^(2)
r = 11 The radial length.
Is the x axis the horizontial on a graph?
YES!!!
The 'x-axis' is by convention the horizontal axis.
It follows that the 'y-axis' is the vertical axis.
This is for a 2-dimensional graph.
In a 3-dimensional graph , drawn on paper ( 2 -dimension) , there is a 'z-axis' . This is shown as an angled line, going 'up' from left to right.
All three axes intersect at the origin.
The coordinates are ( x,y,z,) in that order. The origin is ( 0,0,0).
How are quadratic equation different from linear equation?
On a graph '
A linear Equation produces a Straight line
A Quadratic Eq'n produces a Curved line.
Why is a graduated cylinder better for measuring volume than a beaker?
A graduated cylinder is better for measuring volume than a beaker because it has a narrower shape and more precise markings, allowing for more accurate readings. The design minimizes the meniscus effect, reducing parallax error, and enabling users to measure small volumes with greater precision. In contrast, beakers are typically used for mixing or holding liquids rather than for exact measurements. Thus, for accurate volume determinations, graduated cylinders are the preferred choice.
What is the best airline plane to los angles?
The best airline to fly to Los Angeles depends on your departure city, budget, schedule, and travel preferences. Airlines such as Delta, United, American, Southwest, and Alaska Airlines offer flights to Los Angeles International Airport (LAX).
For the best value, compare ticket prices, nonstop options, baggage fees, flight times, and change policies before booking. A slightly higher fare may offer better convenience or fewer additional costs.

What is the maximum number of sides a polygon can have if each interior angle is obtuse?
Millions of sides.
However, I think you mean 'MINIMUM' number of sides for regular polygons with OBTUSE interior Angles.. The answer is '5' ( pentagon.
Name a regular polygon whose interior angles are all obtuse?
A Pentagon ( 5 sides) The interior angles are '108 degrees; , which are OBTUSE .
NB Regular Triangle = ACUTE
Square or Rectangle = RIGHT ANGLE.
Regular Pentagon and greater number of sided polygons are all OBTUSE.
Which of the following is not a Pythagorean triple?
The simple Pythagorean Triples are ;-
3,4,5, & 5,12,13.
Any multiples of these number is a Pythagorean Triple
e,g, 3,4,5, = 6,8,10 = 60,80,100 et seq.,
How do you find the hypotenuse if you know one leg and one angle?
Remember the Trig. Functions.
Sin(Angle) = opposite / hypotenuse.
Hence algebraically rearranging.
hypotenuse = opposite / [Sin(angle))
NB You MUST know the length of the 'opposite', and the size of the angle.
So if the opposite is of length '2' and the angle is 30 degrees.
Then substituting ;=
hypotenuse = 2 / Sin(30)
From Tables or calculator 'Sin(30) = 1/2 = 0.5'
Hence
hypotenuse = 2 / (1/2) or 2/(0.5)
2/(1/2) = 4 or 2/0.5 = 4
Hence the hypotenuse is '4' units in length.
What is the shape for an angle half turn?
An angle that has undergone a half turn measures 180 degrees. In terms of geometric representation, this can be visualized as a straight line, where the two rays of the angle point in opposite directions. This configuration divides the plane into two equal halves.
What is a 107 degree angle called?
OBTUSE /
Less 90 degrees ; ACUTE
90 degrees ; RIGHT ANGLE
Obtuse greater than 90 degrees but less than 180 degrees
180 degrees arc swept by a point on a straight line
REFLEX ; greater than 180 degrees but less than 360 degrees. ( The 'outside' of an acute or obtuse angle)/
Perimeter is NOT squared.
Squaring calculated the area inside the perimeter.
The perimeter is the addition of the lines that form the edge/perimeter.
Is perimeter squared or cubed?
Neither!!!
Perimeter is the addition of all the straight lines that form the perimeter.
Is the volume of a figure squared or cubed?
Remember a straight line is NOT 'powered/indexed'. a^(1) or just 'a'
For Area , the power/index is 'squared' . a^(2)
For Volume, the power/index is 'cubed' a^(3)
